TWP natural effects vs oil base

We’re staining/sealing a south facing IPE wood deck that is partially covered and partially not and also staining rough sawn, 10x10 pine posts and trusses of the deck in SE Idaho where we have a decent amount of snow for about 6-8mo of the year. We will use the Gemini restore and brighten products before application. I can’t find many reviews on the use of the Natural Effects series of TWP stain. I understand that the top coat would need to be reapplied as frequently as stain of the 100/1500/semi-solid lines if we do use the natural effects. I feel like applying a clear top coat every couple of years would be easier than a new stain coat. Am I wrong? Do you have experience about the absorption and durability of the natural effects products? If this was your home, what product line would you choose to use and why? (FYI - we will be using the ebony natural effects or the charcoal color in the other lines.) TIA.
